Size Comparison
Habitat Comparison
Common Ostrich
Open arid and semi-arid habitats including savannas, Sahel, and dry woodlands across Africa.
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Song & Call Comparison
Common Ostrich

Northern Fulmar
A nasal, cackling 'kak-kak-kak-kak' or grunting 'uh-uh-uh' at the nest and colony. Less melodic than petrels. In flight gives occasional single nasal calls.

About These Birds
Common Ostrich
ダチョウ（Struthio camelus）— 世界最大の鳥でアフリカのサバンナに生息する。飛べないが時速70kmで走ることができ、世界最大の卵を産む。
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
